'Overseer' in the Bible

This is a faithful saying: if a man seeks the office of an overseer, he desires a good work.

The overseer therefore must be without reproach, the husband of one wife, temperate, sensible, modest, hospitable, good at teaching;

For the overseer must be blameless, as God's steward; not self-pleasing, not easily angered, not given to wine, not violent, not greedy for dishonest gain;

For you were going astray like sheep; but now have returned to the Shepherd and Overseer of your souls.
